depende sa iphone 3, 3g ba yan o 3gs? pag 3gs dun na ko sa iphone.
jailbreak? rooting? why fix it when it's not broken. if you know what your doin' knock urself out.
wag mo na i jailbreak. pwera nalang kung hindi abot sa budget ang pagbili ng apps sa appstore/android market na kung tutuusin e mura lang din naman.
performance wise sigurado talo ang w8 dahil hanggang ngayon eclair pa rin ang version ng android os nya... and i doubdt SE will release an update for that phone.
while the 3gs, a 2 year old phone still has ios upgrades.
if your gonna use your phone browsing the web, w8 doesn't perform well.
i'm an android guy i owned an x10, htc desire, lg optimus 2x, desire hd at my current is an se xperia play. my most powerful phone, specs wise was the lg but performed poorly tinalo pa nung x10.
maraming Magagandang SE phones the w8 is okay but if you want something better dagdagan mo lang konti budget mo para sa mas magandang SE phone e.g. xperia series phones.
final advise: iphone 3gs or a high end android phone.
