Why won't my phone to synch music and apps after ios6 update?

Question

I have a 3gs and I just updated my phone to ios 6.1.3 - there was an error that happened in the middle of restoring my phone after the update, but all my contacts, photos, email, messages seem to have transfered ok...everything except my music and my apps. However, when I go to sync my phone in itunes, the option to sync is completely greyed out.  I've tried restoring the phone again after itunes prompts me whenever I plug it in, but after selecting "restore from backup" it never gives me an estimated completion time - it's like it's just booting up without actually doing anything. I've tried syncing via wifi but the option to sync is still unavailable. How do I fix this?

Well you do not have enough space to update to 7.1  You need at least twice as much space as the size of the update file.  You willneed about 3.5Gb  What you could do is make sure youhave a good backup (backup http://support.apple.com/kb/ht1766) then transfer any purchases to your computer using itunes.  Connect your phoen to itunes on your computer, select the phone form the left then click on file in the menu bar and then devices and then transfer purchases.  After that you will need to delte more things from your phone.  Looks like it might have to be music and/apps that you have to delet as you have used ablt 5 GB of dat aon your phone.  the apps should be on itunes in your computer and you can sync them back.  camera roll photos will be in the backup. Any other photos that you transferred form the comptuer to your phone should be on your computer and you can sync them back.  Once you have made enough space do the updata  then restore from the backup and then sync /transfer back what you need.
