Seriously inquiring into buying an unlocked HTC Desire S from Vodafone or another UK carrier, unlocking the IMEI and then putting a Canadian SIM card (Bell or Telus) into it. Anyone with hints/tips/warnings? Will most features/apps work on the 'converted' phone? Or is something like this a little too advantageous? The Desire isn't new enough for me, and the Desire HD is much too large. I fear the Wildfire will give me too many lagging problems (fast texter, loads apps slower) and the Incredible S is WAY too big. Thank you for feedback!
