IMessage and Data Problems for iPhone 4?

I'm really starting to get mad now. I have an iPhone 4 with C-Spire and I recently got a new phone since my old one cracked the other day. Ever since, my network (I guess you could say?) has been intermittently flashing on and off. I get "could not activate cellular data network" when I have 4 or even 5 bars and Wi-Fi! I text all the time and the main person I text has an iPhone 4 too (both of us are running iOS6) and we have to constantly send messages as a text because imessage simply WILL NOT send, no matter how many times I try to resend it when the exclamation mark shows up. I'm pretty tech-savvy and have tried everything I can think of under settings, but still no solution. It worked briefly earlier and now isn't working. I'm having to do this over Wi-Fi because I can't even get on the Internet with 3 bars of 3G! Can someone please explain this?

Can I replace my back plate for my iPhone 4s?

There's a website that will selling a SOLID black iPhone 4s back plate replacement. That is the exact thing I want no logos or numbers just solid black. Unfortunately the only one they have is for the previous iphone 4 model. Can I still buy it though, is the 4 model back plate compatible with the 4S?

IPhone 4 jailbreak problems, can't start phone?

I just got an iPhone 4 from a friend to use because my phone broke. Verizon said the phone has a jailbreak on it and they can do nothing to fix it. When I try to turn the phone on, the apple symbol appears. After a few seconds, it bursts and turns into what I think is the Android symbol, it looks like a little robot type thing. A small loading circle appears over this symbol, and then freezes and stops spinning. It stays frozen on this screen and I can't do anything. I tried connecting it to my iTunes to restore it, but it won't even connect. Does anyone know what has been put on the phone, or what I can do to try and fix it? Any kind of answers would be helpful, I'm clueless on this.

How much data do i need on the iphone 5?

I'm getting an iphone 5 and was wondering how much data i need per month for my plan? I don't use my phone to download apps or watch videos or listen to music. I do that at home on my computer or on my phone but using my home Wi-Fi, not 4g. I only use my phone heavily for twitter (Like 15 tweets a day and refresh the feed like 10-15 times a day) facebook (Post 1 status, refresh feed twice a day) Instagram (Post 1 pic a day and refresh feed 1-2 times) i also occasionally use the maps app to navigate to places but i only use it around 1-2 times per week

Is 100mb or 200mb enough?

Why is my iPhone 4S not displaying the status bar when I'm on Safari?

I was on YouTube and then I look up and the status bar on my iPhone wasn't there! It's there on any other app but on Safari it totally disappears. What is wrong with my iPhone?

Added (1). No my phone is new. I got it for my birthday about 6 months ago. It was in its box and my parents got it at best buy. So it's not jail broken.

Is 8GB enough memory for the iPhone 4?

So, I'm undecided between the iPhone 4 8GB. I have an iPod Touch 8GB and I never had to erase memory but I only have 2.8GB left.plus I only have 100 songs. How much memory can 8GB hold? I have on my phone 2000 pictures, 350 songs, and 20 apps. I really want the 4S but, its a little on the expensive side, does Sprint have the 4 in 16GB?

Added (1). All i'm planning on having is a lot of pictures, around 500 songs, and 50 apps MAX, I mostly only use Insagram and Twitter.

Getting iPhone for Christmas

I'm upgrading my current Android Samsung phone to an iPhone for Christmas! (Android's suck!) :P lol. Well anyways, I was wondering if Iphones have any free music downloading apps similar to GTunes that Android has?
