We heard way back at CES that a GSM Pre was in the works, but not until now have we heard who exactly in the world would be using it. According to confirmation received by T3, Palm is gearing up to disclose the whos, whats and wheres behind the UK launch next week, meaning that we've got seven days (give or take) to twiddle our thumbs until we know which carrier (O2 or Vodafone, most likely), how much and when it'll be available for purchase.
