Im debating wether to buy a new 8GB or 16GB iPod Touch on eBay (new for 100 unde retail) or for a bit more, an unlocked 2.5G iPhone. The only thing stopping me from getting the unlocked 2.5G phone, is well, the unocked part. Will Apple somehow brick all iPhones that are unlocked? (except 3G iphones) Will an unlocked iPhone still be able to download the 2.0 firmware (will it be free?) and will they still be able to download from the App store? And will they be able to access the internet (both WiFi and 2.5G) correctly? Down ehre in Aus, could I, for exmaple, browse the internet on 2.5G with Optus? Despite being slow, I'd still like to have the option. Overall, what Im asking, are there any disadvantages of having an unlocked 2.5G iphone rather then an officialy bought locked 2.5G iPhone? Can Apple even tell?
