Yep, thanks. I deleted it cos it was getting over complicated for such a simple issue.
I'll look at your link tonight. I do have the manual, but it's a pdf of 97 pages. Just what us old-timers hate in the middle of plumbing, gluing woodwork, fixing . . . well, everything.
I persevere with this phone cos I've got so many things like 3 batteries, two chargers, two headphones etc., etc. I won them due arguing about the 4 phones they sent be before I got a good one.
The T-mob bloke simply missed out a method of getting me onto wi-fi to initiate the total out-of-the-box style reset of the phone. Prior to that, it was chicken-and-egg trying to do it via a signal it couldn't initiate.
Motorola I have to say, were very helpful, though don't know what I'd have done if I'd not had a router.
