Trying to unlock my iphone! (UK)?

My grandad gave me his old iphone 4 and he was on EE. I was on O2 and my whole family and all my friends are on O2 so it costs a load to text them and I just generally don't like the network. I went to get it unlocked and it was going to cost £118! I've tried to look for other solutions but can't find anything. I would be willing to pay anything up to £50 give or take. Any suggestions would be great thank you!

Best luck.

If your granddad rings EE and tells them what you want, they'll do it for you (free).

What you will need to do is first find out your mobile phone's IMEI number. You can find this by typing in *#06# and then hitting the enter or send key on your Iphone. This number is completely unique to your phone and will be used to generate or calculate an unlock code for your iphone. Keep in mind this only works with GSM or SIM based phones and not CDMA ones.
