I bought and own this phone myself. I am very happy with it. Cheap but very functional.
The battery lasts about 5 days, if you don't chat alot. The screen is clear and sharp and you can add a mini SD card which you can load wallpaper and music to the phone.
Because it supports 900 UMTS, you can use it as a modem too. But I only get about 400Kbps DL speeds.
Bought the GF one last week and she's happy too. R399 at Cell C stores.
But the other day I saw on TV selling it for R299, wasn't sure if it was PEP or Ackermans, go take a look there before you buy it from a Cell C store.
