samsug galaxy got some problem

[Nirmal]

so i bought the mobile from HK. but when i arrive in the uk(i first opened it in the airport), the phone keeps on crashing(frozes, then shake and then restart)., the phone is on andriod 2.2.1, i dont know if it is stock Firmware or i updated it. all i know is that it will say "XXX" process forcibly closed or somethings, it happen more frequently when i access the andriod markets, and i cant install some apps such as angry bird, and some other games.
Can it be cause by a failed update? since the wifi in the airport is quite crap.
is there anyway to fix it? like down/up grade the firmware?

An update will probably fix the problem. It usually does.
