Just had a similar problem here in Egypt. After the packet connection was working for a while and I tried to fetch some MMS with fMMS, I do not connect at all to the packet connection (fails), and I find it more tricky sometimes to even connect to wireless connections! I think it has something to do with fMMS.\

Edit: My exact problem now is this. After using fMMS once in PR 1.2, my packet data connection NEVER connects. It fails after trying for 2 seconds! It was fine before that. Any tips? I'm in Egypt on Mobinil Network.
