No matter how good the Japanese cellphones are they all feature the same problem cause by the major operators (DoCoMo, AU, SoftBank): the SIM LOCK! If ever you want to quit one and test the other then you have to buy a new cellphone! Hopefully HTC is now giving each customer the possibility to change thanks to the Advantage X7501 or P3600 (with GPS), both are WCDMA-HSDPA and in Japanese…can’t have it all!
