Like me! My very first cellphone was a Sony Ericcson. It was a GSM bar phone, in 2004. Got it free with the AT&T employee plan. It saved me once. I was in a car wreck on the freeway and my gf was using AOL (ha) on the only phone line at my house so I used my tiny Sony Ericsson to contact a co worker friend on msn messenger (this is seriously making me sound old) and told her to IM my gf to get off the computer/phone so I could call about my car accident and get help. It wasn’t a smartphone, either, but it did the trick there.
Then I got one of those Sony Walkman phones a year later, it was excellent for music.
When I worked at one of the US’s major wireless carriers as a manager, I snagged an HTC phone when it was one of the first Android phones. It was small but very cool. I’d been using an iPhone 3G at the time and as soon as I played around with the Android, I knew I had to have it, and never looked back! That was 2009 I think.
