I went for a walk in the woods today. It just snowed yesterday and today was sunny low 50s(Farenheit) and I had a little snowball fight. My phone didn't get wet at all. It just got cold now whenever I try to play a game, send a text this blue rectangular box shows up saying "charging is not supported with this accessory" and it's very annoying. How can I fix this?

Can you Remote Control your iPod, iPhone or iPad Music from your Computer?

Recently I have been using my iPod Docking system allot to play Music on (Mainly Spotify, Because I Just got it!) and I want to be able to control the playback (E.g. Play, Pause, Rewind and Fast-forward) from my Windows 7 Home Computer for free, But is there a way to do it? My dock doesn't come with a remote sadly so this would save me allot of time getting up walking across the room to change the song!

Why is my Iphone not sending as Imessages and receiving iMessages from one person?

I'm texting my wife and we both have iPhone's and she is getting the messages as an iMessage but the ones I'm sending her on my end show up at green.
Sometime it will go as blue, get the little red exclamation point then send as regular SMS.
I'm texting someone else too and she has an iPhone, and she is getting mine as regular iMessages and mine are sending as regular iMessages.
Why aren't they sending to me wife as iMessages?

IPhone 5 cases similar to Otterbox Commuter?

I want to get a good, durable, and cool looking case for the iPhone 5. Everyone keeps on pointing to the Otterbox, and my friend has the commuter and i really like that, but it's too commonly used and I would like to get something a little different. The main thing that I like about the commuter is the material on the outside (i don't like the rubbery outside), and I also like that it actually protects the phone.

If someone could give me suggestions as to other cases that are similar to the Commuter that would be great.

P.S. I'm looking for brand names and/or model names.

Sprint, IPhone4s. 2 year contract?

I want the iPhone 4s from sprint. My mom wants to sign the 2 year contract and the people who work there said they had to check her phone credit. My mom doesn't have the best of credit, but they said "phone credit". Does that mean they'll check only her history with phones or everything?
