i lost my phone at school today... i think someone stole it :S hope not! i have seen a phone on eBay i would like to buy but it's locked to vodafone and my Crazy johns Sim card which i need a replacement for. will they work together because I've heard they are the same and when i bought my Sim card plan "Sim Only" they asked if i want vodafone or crazy johns... i think anyway... or will i get an error with the phone? please answer ASAP! i have 4days until i can't buy the phone!!!
