Ok guys i have a some questions regarding this hardware hack for the iphone4. 1.If i am on a Vodafone uk contract sim and i want to use a pre-paid sim will this work? 2.Will this work for 4.3.3 and do all the Gevey sims work for iphone and 4.3.3 or is it a specific one? 3.Is it possible Apple could release an update that would render this unusable? I want to ask people in the uk with any experience with this in particular. Have you had any problems with connectivity and loss of 3g? Thanks!
