Apps can't connect with OS different than 2.2

Question

Hello, I've looked around the forum and I see common issues as mine but not the same. So my problem is from updating my Ipod Touch 2G 16GB with ANY OS. With the original 2.2 I have no problems at all, but since 3.0 is out every single update I've tried is preventing me from using Wi-Fi. The OS3 was preventing me from using entirely the internet if I remember right, while the OS4 is preventing me from downloading apps and connecting with the current ones. I can browse around YouTube and web pages, I can browse the App Store, but I can't download anything. When I try to download an app, it's just trying to connect until I stop it. When I try to run apps that I already have, by restoring from Itunes, they just can't connect to internet, it says that there is no active internet connection. The Wi-Fi is up and running, just not for the apps it seems.
So I've tried reseting the network settings, full reset, restore, WAP/WEP/no password on router, and no result at all. I just keep going back to 2.2 after every update because I need my apps to be able to connect to internet.
Because Apple were very unhelpful I am looking for any input that could help.
Thanks in advance.

You can get support from Apple by visiting an Apple store or by calling technical support. This is a user forum.
I am going to suggest that you work on your WiFi problem. There are no inherent OS problems in 2, 3, or 4 that would cause what you are describing. If Safari can connect and you can browse, you don't have a problem. If you can send/receive e-mail, you don't have a problem. If you can connect to the App store but can't buy/download anything, then your problem is with the App store.
But if you do have WiFi issues, then you can try the following (works on all versions of the OS):
1. Reboot your router (unplug it from the power)
2. Reset the touch network settings - tap Settings > General > Reset > Reset Network Settings
3. When your touch restarts, tap Settings > WiFi > Other and completely re-enter your network name, security, and network password.
You can always check to see what your internet connection is up to by tapping Settings > WiFi > and then tapping the blue ">" next to your network name. If your device IP address starts with 169.x, then your most likely problems are with your router or the encryption system you have chosen.
If your iP address is the expected 192.168.x.x series, then your problems may be with your ISP's DNS service. If you know how to work with your wireless router, you can always change the DNS to something a bit more reliable like OpenDNS.
If you still have problems after you try the 3 steps above, post your network configuration for us - type of router, encryption used, etc.
