Hi I have a 1.1.1 with 4.01.13 firmware iPhone jailbroken with a ATT SIM working fine!! I am going to travel to Europe in a few months and I want to use my phone over there!! but I have a few questions that I want to clarify before I unlock it!! I don't want to upgrade to 1.1.2 right now!!

1. What's the difference between anySIM-1.1 and anySIM-1.1p?
2. I am happy with my ATT service!, I am going to use the ATT SIM here,
but I want to be able to use another SIM in Europe!! If I unlock the ATT SIM would work just fine? I am satisfy with the service as I have it right now!! I asume it would not change right? YouTube, Itunes Store
3. Do I need to get a lockdownd patched version to be able to swap SIM Cards without problems?
4. Does the anySIM-1.1 modifies the Baseband? If I do a restore do I need to rum anySIM again?
5. If I do a Restore can I get a Fully unmodified phone? Just as I bought it?
6. Can I upgrade to 1.1.2 without problems in thr future?

Thnaks in Advance!!!

Can Someone clarify this points for Me? I don't want to mess up my phone!!!
