Okay so on June 21 me and my fiance' both upgraded our iPhone 3GS to iOS4. Ever since then we have a list of problems. Can't answer calls, no mms, no internet at all except wifi, sending messages without pressing send, ignoring calls on first ring, no email access. So if there is anyone out there that can please help us please please please give us some information

ps i did a complete restore from iTunes on my phone and it really didnt do anything at all except take 80% of apps out my folders that i spend 2 hours doing and it went threw all the steps so im not sure why it didnt work?
