My choices r e Samsung 8MP phone, F480, Sony Ericsson C902, W595 and HTC Dream. These r e phone which i will buying. Yesterday, my cpu is on service cos my power supply problem or don't wat i heard the person who took my cpu said there he will call us or when e thing is ready in e next 3 workin days. 4 now nothin much 2 do juz wait 4 my cpu 2 come back n i hope is e hardware problem, by e way must pay cos out of warranty ardy. I still don't know which one i should choose continue using my prepaid or sign-up. I know sign-up will be every month pay don't wrry i will choose wisely. All e phone in my choice not bad, some r good n some ok lah i want 2 buy cos my old hp quite bored n other reason is 2nd year new stuff.
