Thanks for the above, appreciated.
The thing is, although I can follow what you say, I'd be a bag of nerves trying to actually do it, and if I hit a snag I'd be bollocks'd and odds the odds on favourite to brick the phone, if I did that I'd have to leave home before the wife found out that 300 quids worth of phone had been tuned for maximum smoke.
Hope you don't mind me saying this SU, but you lads discount the expertise that you have, even though it's laid out for all to read it's still Greek to the average guy, as mentioned I can follow "hear the music", but I know for sure I wouldn't look good trying to dance to it.
Add to that, (as you say) it gets trickier when the phone is already branded, as mine is, just my luck to finish up with an Orange phone, the toughest of them all to debrand
What I can't figure out is why the local shops in Blackpool shy away from even attempting to do the job for me ? the technicians in places like that are usually pretty decent, well at least in unlocking phones.
The bottom line is, I'm just a retired Postie, and although your footsteps seem clear enough, them damned IKEA flat packs that the wife keeps bringing home test the limit of my technical expertise, and I don't fancy giving the phone a "tap with the hammer" if it's not quite right.
Have to say that although this is out of my league I can follow most (if not all) of it, and I enjoy reading the write ups in here.
Best thing for me is to find a shop or a techie who can do the job, I'd rather pay to have the phone sorted than brick it
Thanks again SU for your time and consideration, it's valued and appreciated.
