I'm a standard (though long-time) customer of Vodafone, and when, a month or so into having my first HTC Desire it started to restart regularly, I called them up, explained the situation, said I cannot do without it at work, and they caved in and gave me a next day like-for-like courier provided replacement, at work, free of charge. I do love Vodafone service. I had read online about all the problems people were having and how slow the turnover was, so there was no chance I was putting up with that
