Iphone Jailreak 6.0.1 3gs shutdown itself?

I had restore my Iphone 3gs to 6.0.1 from 5.1.1 just today? It is New boot-room and firmware version is now 5.13.04. Using RedSn0w latest version, I had it jailbreak [You know the stuff, for redsn0w you select ipsw 6.0 for stopping the keylist error]. Using Cydia, I had ultrasn0w installed as well. [My phone needs JB and unlock for working: P ) It is working now, only problem is "It turns off itself if I put SIM in. It is working fine without SIM, but if I insert the SIM, it just turn off. Then I restart it again using Boot option from redsn0w, but after couple of minutes - it is dead again. Battery is full and I have installed anything else yet.

Please advice.

Is 2gb of data alot or a little?

I just got an iPhone 5 unlocked and I have an unlimited talk and text plan with 2 gigs of data for $60 a month on Tmobile. I think the plan is great but i don't know if 2 gb is too little. I have Wi-Fi at my house. But I do use the phone all the time. Since dec 27 I've used 135 mb. Is that a lot? This is my first smart phone lol

Is it possible to add multiple images to an iPhone 4 wallpaper?

It may seem cheeky, but I wanted to know if I could have multiple images for an iPhone 4 wallpaper. More specifically, I was curious as to whether or not I could have a set of images cycle every time I viewed my lock screen.

Is there an app or setting I can use to do anything like this? My iPhone 4 is jailbroken, but it runs on iOS 6.
