Where can I unlock an iPhone 4?

I know there's probably no way. I have tried to deal with Rogers for a factory unlock (It's a Rogers phone), but they seem to not want to unless I sign up with their service for a month and I'm tired of dealing with their HORRIBLE customer service and will never go near anything to do with them. The SAM unlock tool is patched and as far as I know that, at one time, was the only hope. Its running 5.1.1 on the infamous baseband 4.12.01 and I this is just the last beacon of hope before I get rid of this thing.

How much money to bring for Warped Tour?

Okay, so I'm going to Warped Tour on Sunday and I was wondering how much money I should bring for food, water, merch, etc.

Also, this may sound stupid, but, I have a pretty nice camera, and an iphone, and I was wondering is it safe to take them with, will I have to worry about pick-pockets, or anyone stealing my phone/camera/money? I've never been to an outdoor concert before, so I just wanted to know what to expect at the concert: D

My iPhone 4 suffered heavy water damage, will it be okay?

I went in the pool with it not realizing it was in my pocket. I was in the pool for about 5-10 minutes before I realized it was in my pocket. It was on when I went in the pool but was off when I got out. I now have it sitting in a bowl of rice and I plan on leaving it in there for a week, changing the rice it's in every 24 hours. Does anyone have any insight on this, like if there's any hope of it being okay or is it done for?

How to call pakistan from america for free?

I live in america. I have a no contract iPhone and i text my loved ones with textfree/pinger. I want a way to call them without them having to call me but unfortunately i don't have a contract. Is there a way i can still call them? I've tried so many apps. And don't tell me to get a contract or something, I have another phone but my parents would get suspicious if they saw long distance calls to there and wonder who i was talking to.
