.... and still have the same phone number.
Crikey that's impressive, I changed my number a few years ago just to press reset on spam calls!
First mobile phone Nokia 6110 - incredibly robust and no worries about cracked glass front or back, was a bit bulky though.
Second mobile phone the lovable 3310, generally thought to be more robust but the colour swappable covers would sometimes crack and I replaced the rubber keys a few times, and the back battery cover could end up coming off a bit too easily after a few drops. All parts that could be easily replace though. I still think this is one of the best phones I've ever had.
The one I never had but really really would have liked was the motorola razr in 2004, I just wasn't cool enough (and didn't earn enough) to justify it though
