I am having the same problem with it not updating, I am on 3G and wifi and it will not update to google play and it says I have no apps downloaded. I have 3 tablets all the same and this is the only one that is not working.

It also will not let me sign into google talk but it updates email.

Thanks in advance

I finally managed to solve the problem. Just follow these steps, but bear in mind that i'm using a custom ROM so it might be a little different with you. Go to Settings > Wireless and network > Mobile networks > Access Point Names (or APN). K, now select the APN that u are using. (I chose MTN Data since i'm MTN. Now go to "Proxy". There should be a number in there. k, delete everything that's in there and leave that field blank. Go to "Port" and clear everything as well. It worked for me.hope it works for u too. Let me know.

 

Thank you SO much! Been having this problem on my Galaxy P7500 ever since I updated to ICS (Italy) and I am in ZA. After 2 weeks of deleting and cursing I finally found your advise and it worked!
