I'm in a bit of a situation. I live in Canada. I leave to the US and Poland in about 17 hours on a two month trip. I have spent the better part of two weeks trying to unlock my iPhone to no avail. I now need a phone. I have turned to my city's classified adds where there are several android phones for sale. My issue is this: I am fast approaching the point at which I will no longer be able to meet someone to buy a phone today, but I don't know what I need.
I am aware that the answer to my question is out there on the intersphere and forunets, but I'm not confident that I'll be confident enough to buy a $250 phone at the end of my research. Therefore, I'm turning to to forums to see if someone knowledgeable can quickly answer my questions so that I'll be able to run out and buy a phone right now.
The phones on the classifieds that I'm looking at are:
A Galaxy S2 on contract with Bell Mobility (Canada) - $350
A Galaxy S 4G factory unlocked - $280
An unlocked and rooted Nexus S - $300
HTC Desire broken proximity detector - $100
Nokia Lumia 710 - $200
HTC Wildfire S unlocked - $220
Is the phone unlockable?
Will it work with a pre-paid SIM in the US? (which carriers, if known)
Will it work in Poland, France and Italy?
I'm computer savvy but sadly my knowledge is deficient in this area. If anyone can answer these questions, it would be much appreciated.
