So I went ahead and got the phone I talked about buying. It seemed like the time, I'd just got paid for a job and the price had dropped. I don't understand how they can make money when you buy the phone for €80 and then get €90 free credit.
As you can see it has a camera, which may be useful. It also has some PDA features, so I may look at retiring my Visor. In a perfect world I'd get a Treo, but none of the networks is selling them and I can't afford one without a contract.
The other problem is you have to buy a separate cable to sync to a PC. That seems to cost nearly as much as the phone. I'll just have to see.
