I will be in Japan for almost two years. I want a nice android smartphone, but unfortunately, US phones don't work in Japan, and vice-versa. So, it makes no sense for me to invest in a phone here (nevermind the yen-USD exchange rate). However, I've been dying for a replacement for my 6-year old PDA (Dell Axim X50v), and I'm willing to spend $500-ish on a similar-sized device that runs a modern version of Android. I need something to read a few ebooks at night, play some across-lite puzzles, and perhaps browse the web via wifi. I'm considering buying a Photon 4g, as it sports QHD resolution, and has many other neat features I find enticing. Obviously, I'd be using it with NO contract, but I think the wifi would still work, which would be enough to hold me over for my stay in Japan (I am REALLY needing a replacement for my PDA!). I'm doubtful that the GPS would work, as it advertises "aGPS", meaning "no REAL GPS" if I'm correct. That, and I doubt google maps would work without 3G/4G for the map image downloading. Finally, every non-contract Photon 4G I've found online comes with that limiting "Sprint" caveat. Would this phone, even a non-contract version, be limited to Sprint's networks and data plans when I ever return to the USA? If there's a better solution, such as one of those Archos MIDs, please let me know. I'm at a loss for ideas right now.
