Does an iPhone require data to send group mms?

I have an iPhone on ios 6.1 and I seem to e missing parts of group texts, and even receiving them up to a day later. I recently updated from ios 5, and before I used to be able to use group messages using only Wi-Fi (I turn my 3G off at home and only use Wi-Fi). Now when I'm only on Wi-Fi I'm missing group messages, but when I turn my data on I will get tons of messages. Is this something new that requires data to use group messages?

Added (1). Why could I previously get group messages using only Wi-Fi but now I can't?

Problem with iPhone battery?

My iPhone 3GS is going dead anywhere from 29-34% battery life. It's done it for two days. Looked online for an answer and all I could find was to do a hard reset which did not work. After it dies, if I try to turn it back on it shows the dead battery with the charging symbol. When I charge it, it comes back on and says the same percentage it said when it went dead. It's like the phone recognizes 29% as 0. What's the problem?

What is better? IPhone or Samsung Galaxy Smartphone?

Text are going to my old iPhone

Hi
so I have an old iphone 4 and now i'm currently using galaxy s3
i still use my iphone as like an itouch and yesterday i upgraded my iphone and this thing popped up and i pressed ok or whatever even before i could read it.
After that whenever someone with iphone tries to text me, it would go to my brother's iphone! (because my brother and i share same apple ID)
so i told my brother to check off my number from the send&receive menu
and now he doesn't get it anymore but it started to come to my iphone.
So i turned off my iMessage… But I still don't get the text on my galaxy s3.

What can I do to fix this problem/?

I just got the Blue Screen of Death on my brand new Windows 8 HP laptop?

I just purchased an HP Laptop with Windows 8 I have had it 3 weeks or so now. I do use Iphones, I tunes, etc. So I'm not syncing anything, quite honestly I don't even know what that means. ( I read it after I googled what the violation meant) I only use my computer for school, skype, etc. When I called Best Buy to discuss it, because I had a feeling it was nothing good, they said "oh just keep an eye on it, it could be many things" can anyone tell me their experience what the blue screen of death means? I got the WDF_Violation. I just hope I didn't purchase a lemon. Thank you for giving me your opinion

Added (1). I purchased it From Best Buy, so it is under warranty, for 1 year. So I will not have a choice but to take it back to have them fix it or replace it. I backed everything up.
