How to Make My iPhone 4 CDMA Sprint work with my GSM carrier?

I did not know what I was doing and bought a Sprint CDMA iPhone 4 when I actually needed an iPhone 4 GSM. Is there any way to use the CDMA iPhone on my GSM network. Gevey has some unlock solutions but I do not understand the terms jailbroken or unlocked. I want to learn how to repair iPhones but I'm totally new to this… Any help would be appreciated.

My iphone 4 is turning on and off every 10 or so seconds?

My iphone is turning on and off every 10 seconds or so. This means i haven't got enough time to backup/restore via itunes as my iphone keeps disconnecting from itunes when it turns off. For some reason when i access my iphone from 3rd party programs like ifunbox or iexplorer i can still access my iphone even as its 'turning on and off'. I've decided the only option left is to delete everything except for the CORE/ESSENTIAL files… I want to 'restore to factory settings' MANUALLY via ifunbox. Can someone please tell me if this is possible and if so, what are these 'essential' files that i must avoid deleting.

IPhone 4 No Service, but got 3G?

I recently purchased a second hand smash iPhone 4 8gb. I have since replaced the screen. The phone worked well for 2 days, however when I woke up this morning and had No Service, but did have 3G. When I shake the phone (with my fingers over the exterior buttons to ensure it's not them) I hear a light rattling inside the phone. I read online it could be part of the motherboard near the battery connector, however, the phone worked 2 days prior to the change, and I have checked the inside and at first glance can still see the blue bit I read about. Since I have been writing this, I have also lost 3G. I'm on Giffgaff, and next to me I have a Blackberry with a Giffgaff sim and that has full bars of connection. I have also tried a hard reset, and turning airplane mode off and on. Any suggestions?

Holiday settings on iPhone 4?

So I'm going on holiday tomorrow and I need to know which settings on my iPhone 4 I need to change, so that I don't get charged any money when using my phone abroad. I don't need calls/texts/3G, just to be able to use Wi-Fi.

If anybody also knows if iMessage would cost, that would be great.
