The UK mobile carrier, O2, is recalling their X1 handsets because of a potential charging fire hazard. Owners of the X1 are being recommended to stop using their phone immediately and return it to O2. In exchange the users who return their fire-faulty phones will receive the X2i handset. All of the X1 phones will be rendered useless on the O2 network beginning on Monday—to prevent any kind of damage or harm due to malfunctions with this phone. If you happen to be one of the users of this phone, you can visit the O2 site for more information.
