I'm planning on buying an Verzion GSM Unlocked Bold 9650 from the US as their practically the same as the 9700 but at the fraction of the price. I'm currently on a Sim-only contract with 3 UK and seeing as 3 sims are fairly new, I was wondering seeing as the phone is unlocked, can I just pop my 3 UK sim into the 9650 and all features will work? Such as 3G, BBM, BlackBerry Internet service etc.
