I have this phone for the last 18months- having come from a Sony Ericisson. I bought this on contract as it seemed to have the features that I required:

GPS
Large screen
Large memory 8gb
Multi-tasking of apps
Download apps
Wireless (3G and wireless)

I found that this phone had all of these features and more- so I ended up going for this when my contract was up. I found that when I got the phone, the GPS was very slow- I performance update on the phone and found that the performance was greatly improved. Downloading applications onto the phone is very easy using the 3G or wireless on the phone- you have a choice to install onto the phone or the extra 8gb of memory. The MP3 player on the phone doesn't have that many features- but it does the job well. The extra buttons on the slide for skipping and play/stop/pause are very useful. The fact it uses a 3.5mm jack for the headphones means that any headphones can be used with the phone- which is really useful. It also comes with a remote which can be plugged in to this socket and used for hands-free usage- though should not be used in the car.

Overall however after having this phone for nearly 2 years- I cannot wait to get a new phone. I have found that certain small things really annoy me about this phone. For no apparent reason the phone will lock up or go very slowly until it is switched off/on again. If you add words to the txt dictionary then once you have turned the phone off/on- then it will lose all of these! I cannot wait to get a new phone!
