Delivery first rate, but to the phone; I struggled at first trying swap the operating system over to Android 2.2, but once I found my feet it was relatively easy (tho it voids warranty so I was nervous).
For the price it's an amazing bit of kit - if you change the operating system, tho the orange stuff might be ok - you really want a de-branded Android system.
Sadly all the OLED models have been sold - only TFT left, but it still looks great.
I don't know if play would take exception to me giving the guide I used a shout out - so I'll just say that there are a few imitators out there but once you find the forum where others have copied from you'll be fine.
All the unlock code/operating systems are FREE - don't get dupped.
A final tip - use the Wifi connection to access the Android market (not the orange app store - tho that can't be connected to via wifi anyway!!!) to get Astro file manager and advanced task killer which will aid your upgrade, good luck - tho all alterations you make are at your own risk, do your research!!
