StraightTalk Data and MMS problem on iphone3gs?

Okay so today i got the straighttalk unlimited plan with my sim card and i installed it fine into my iphone 3gs but i don't want to jailbreak it because i already upgraded to ios 6 and i have tried to change my apn settings but its been very difficult and i finally got it to work but it said "E" instead of 3g and i tweaked it a bit and now it says "3G" but whenever i turn my Wi-Fi off the internet won't connect. MMS messages won't send either. I would consider jailbreaking it if it didn't harm the ios 6 or my phone. Please ANSWER! EITHER TO Help WITH MY APN SETTINGS OR WITH THE JAILBREAK Thanks

Added (1). I tried to find cellular network settings but with the new updates we don't have that anymore! My "3G" shows but its not blue like its supposed to be

My iPhone 4 won't update and the sound doesn't work, what should I do?

I have had my iPhone 4 for a few years now and recently started having some troubles. It hasn't been jailbroken and is currently at iOs 4.2.8--it hasn't connected to iTunes in over four months. The phone shows up in windows (I have a dell inspiron) so I saved all of my photos, but itunes can't find it so I'm worried that I will lose all of my music if I have to do a factory reset. I bought albums on iTunes a long time ago and they synced to my other itunes, but I don't have that computer anymore. Will I be able to get those back without having to pay again? Today my sound refused to work. It randomly comes on in a breaky, creaky sound.

Iphone stuck in recovery mode after trying to update to ios 6

I went to update my iphone but did not have enough free memory for the update. I got a message up saying it was in recovery mode so I need to restore it but when I click restore the only option is 'restore and update' but of course it won't update because I don't have the memory. I have tried restoring it anyway many times, restarting it many times, turning it off and back on, resetting it, unplugging it and plugging it back in, the lot and nothing works. When I unplug it from itunes my phone just turns off. Is there a way to restore it but not update it? I don't want to download dodgy applications off the internet please.

Shattered the back of my iphone? Where can i get it fixed?

I dropped my phone today. The whole back is shattered. Couple of my friends were telling me where they got there's fixed. It's really expensive though. I was wondering if i should just order the back piece and do it my self. Do y'all recommend that? If yall do what website should i order from? Or should i pay for someone do it? I have the iphone 4 not 4s.
