you can't, nor do you need to really.
that guy is on cricket, he should be happy it works at all, this is a verizon phone.
i see a lot of people getting so upset
there are 2 groups here
people who did it, and people who are waiting
the people who did it, cool, i did it too, awesome, we have 2.1 and will be getting the OTA when it is final...no need to debate the merits to those who choose to wait, it is their choice.
the people waiting, cool, awesome, no worries, if you want to wait that is no skin off my back, your self control is a great feat indeed. im sure you will be elated with the 2.1 OTA.
so there you have it people, chillax, no reason to try and beat someone to submission, there is not right or wrong, only choice.
