  • Is there any different between the US unlocked Iphone 4S and the Australia unlocked Iphone 4S?

    I read that the unlocked iPhone works only on supported GSM networks, such as AT&T in the U.S. When you travel internationally, you can also use a micro-SIM card from a local GSM carrier. Did it mean that the Australia Iphone uses the micro-SIM card or work differently? I did not any information about that.

    Well if you purchase it you can call internationally with roaming chatges if you purchase it from Australia i assume it will be unlocked anyways.

  • Are there any differences between 64-bit / 4.7 sdk and 32-bit 4.6 sdk?

    I presume the answer is no, but I need to be sure before copying across (and then deleting) the SDKs directory from 4.6.
    EG: I have a 64-bit laptop that I have just upgraded to 4.7 premium and I want to move my entire collection of SDKs across so as to support the range of legacy products I have with different customers.
    Will I encounter any issues or difficulties with simply copying the directory across from C:\programme files (x86)\adobe\adobe flash builder 4.6\sdks to C:\programme files\adobe\adobe flash builder 4.7\sdks ?
    Cheers,
    G
    (Ps: I did a file compare using CompareIt (www.grigsoft.com - which is excellent, btw) and the only changes I see are a different line feed character. Not sure why that would be, but it looks like files are otherwise identical?)

  • Is there any difference between an HP Photosmart 7510 and 7520?

    Is there any difference between the HP Photosmart 7510 printer and the 7520?
    I have tried asking HP. They were not able to help. Presales advice for domestic customers appears to be virtually non existent in the UK.
    All  I know is that Argos deal with Ingram Micro to get the 7520.
    Is the 7520 just a marketing ploy - selling the same product for a different price? 

    Yes there is a difference. They are not the same; however, they are based on the same platform (engine).   The 7520 is the newer model which just replaced the 7510. 
    The main differences is the 7520 includes a hardware fax  built-in whereas the 7510 used the efax utility in order to send faxes.  This essentially allows you to fax directly from one fax machine to another without using a server based method.
    Other features on the 7520 include addition of a Scan to email feature as well as the addition of a USB 2.0 port on the front of the printer.
    You can find the complete 7520 product specs on the hp website:

    Though I work for HP, My posts express MY opinion, and not those of HP.

  • Is there any link between movement types and documents

    hi
    is there any link between sales doc and movement types ?
    is it the only source dependig on schedule line movement type will determined?
    if with out order we are doing delivery how system will determine movement type
    Thanks in advance

    Hi,
    Deliveries that are created without reference to order , contained movement type because to process a delivery you need to have some of the control criteria that are copied from sales document header to delivery document header, as system processes delivery in that way ,that is why you will find default order type is assigned to the delivery document type ie DL. .which helps the delivery document to process without reference to sales document.
    In Addition to above information,
    In VOV4,
    DL+ NORM +   +    -DLN
    In VOV5,
    For Itemcatagory DLN+        --CN
    From this schedule line category CN,movement type 601 is taken during without reference to order –delivery creation.

  • Is there any relation between feilds " reason, code, code group , sub pro

    is there any relation between " reason , code , code group , subject profile'
    Actually i have make "reason" feild has default value ..
    i have to do by RFC .
    Cany any body plz reply from where i have to pick this reason feild and set reason feild has default value has " not started "
    thanks,
    aravind.

    Hi,
    Subject profiles are used in different areas like
    Service
    Complaint
    Activity reason(Used in all documents like sales,service order)
    There is a relationship between Codes, Code groups, code group profiles, Catologs, Subject profiles.
    Do not confuse 'Reason' with 'Code' or 'Subject'(Not subject profile), all are same. In different contexts you call them with different names.
    1. In IMG while creating codes you use the name "Code".
    2. While entering details about activity in any business transaction you call it as a "Reason"
    3. While entering the defect of the problem in Service or complaint doc. you use the name "Subject"
    In all above cases it is equivalent to name "CODE' which you define in IMG.
    Now coming to relationship of above mentioned entities, in any business transaction type customization you can select "business activity" as additional business transaction category. At the customizing header level of this bus. tran. category you are allowed to enter a "Subject profile" which controls your "Reason" field in the business transaction.
    In a similar way for service or complaint order you are allowed to enter a "Subject profile" for entering "Subject" in respective transactions.
    Each subject profile is assigned to Subject profile category like Service, Complaint, Activity reason etc.,
    1. First define catalogs
    2. For each  catalog define code groups and codes( Code, subject, reason mentioned earler)
    3. Create 'Code group profile' for each catalog and assign assign 'code groups' that are relevant for coreesponding catalog to 'code group profile'
    4. Now finally create a "Subject profile" which is the combination of "Catalog and code group profile"
    I think this would clarify your doubt.
    Coming to default value in this reason field, the standard system will not support this. You sholud use some Badi to get this.
    Reward points if it helps.

  • Is There any Relation Between PCD and SSO

    Hi,
      Is there any relation between PCD and SSO, why because if i am try to connect from portal to R/3 in the user mapping i got one error i.e some pcd error.
    pls tell me how to rectify that.
    Regards,
    Jagadish Babu Kanikanti.

    Hi Jagadish
    The PCD is only a central persistance for storing Portal objects. There is no such relation between PCD and SSO that could create a problem. You can however check for the PCD error in this manner.
    1. In the system administration role, choose System Administration -> Support. The Support Desk appears.
    2. Select the area Portal Content Directory.
    3. Click on PCD Configuration in the test and configuration tools. The next screen shows all the parameter values currently maintained for the PCD.
    4. To reload the configuration, choose Reload.
    Hope that helped.
    Best Regards

  • Is there any Similar between Class.forName() and new operator ???

    Plz tel me is there any Similar between Class.forName() and new operator ??? i have been asked this ques in interview

    You probably should have used the other thread:
    http://forum.java.sun.com/thread.jspa?threadID=792678
    To add a little confusion to the matter...Class objects are in fact objects. They're objects representing classes. So, in a sense, I guess, you could say they're similar -- in each you get an object. But in practice Class objects and all other objects should be considered semantically different unless you're doing some pretty unusual stuff. Also Class.forName is more of a factory method than a constructor.

  • I have a web site built by Yahoo Web Site Builder which does not have a Mac version, is there any compatability between Iweb and the old Yahoo program?

    I have a web site built by Yahoo Web Site Builder which does not have a Mac version, is there any compatability between Iweb and the old Yahoo program? If not how do I clear off the old site so as to re publish with Iweb.

    iWeb cannot import published files so you would need rebuild the site.
    Yahoo hosting is notoriously poor and their tech support is awful. I would suggest you look for new hosting and start afresh. Some pointers for choosing hosting...

    If you do choose to go this route, transfer your domain name registration away from Yahoo to your new host.

  • Is there any incompatibility between Labview 8.5 and Traditional DAQ?

    Hi,  I`m using a DAQPad 6020E and the Labview 8.5 Daq assistant don`t detecte my DAQ when a try to create a new task (to create a new virtual chanel). But MAX detect the DaqPad. So, is ther any incompatibility between Labview 8.5 and traditional Daq? Do you know how can I resolve this?
    Thanks.

    First, you posted to the wrong board. Measure is an old add-on for Excel.
    Second, there is no incompatibility between LabVIEW 8.5 and tradtional DAQ. There is an incompatibility between traditional DAQ and DAQmx which is what the DAQ Assistant uses. Make sure that you install DAQmx if your device is supported by it. Otherwise, you will not be able to use the DAQ Assistant.

  • Is there any difference between the 2 different USB cords when syncing???

    I know this may be a paranoid question to ask but I just wanted to make sure.
    Is there any difference between the newer USB cords with the shorter plug (the end that goes into the iPhone) and the older ones with the bigger, square-shaped plugs that you can pinch on the sides to retract?
    Is there a difference in transfer speed, syncing speed, or reliability, or build quality?
    Just asking cuz the newer USB cord that came with my iPhone 3GS is getting frayed and so I'm using the older one instead.
    Thanks to whoever helps.

    No difference except, as you noted, you have to squeeze the older one to remove it. It's important that you do that so you don't damage it or the iPod.
