I hope I am doing this correctly, and apologies if I have not - but new to all this - I was recommended your site for getting an unblocking code for the above phone which has an IMEM : 353768008923059 It is currently locked to Vodafone and I want to put an O2 sim card in it. I am based in the UK. I assume from reading some of the threads on your page that there is a unique number for each IMEM No.? Many thanks in advance
