At the start the phone was quick, responsive and fast to use. however after a few months it can be sluggish and this is made worse by the fact closing an application leaves it running in the background.
The reception is fine and the battery life is pretty good too.
Obviously the biggest advantage this has over its main competitor the iPhone 4/4s is that this has Blackberry Messenger a free instant messaging service exclusively for Blackberry users. This is fine as long as all your friends have blackberrys obviously. Otherwise you have to download a third party multi platform messenger such as pingchat.
The app store on iPhone is fabulous. However Blackberrys App World has very limited content and is far of the Apple App Store and even the Android Market.
The phone has a decent 5Mp camera and video camera with flash and you are able to upload to youtube and facebook easily.
Also the way the messages are laid out is excellent because you can customise it exactly to how you want. Grouping by type such as email/text/facebook notification, or by contacts.
It is also quite tough, I have dropped it on concrete and it was fine, not even a scratch because the back is a rubbery plastic.
Also, the touch screen doesnt always respond straight away to your finger and unlike on the iphone you have to press quite heavily sometimes. On the iphone you can just flick and tap.
Overall this is a great phone, but if your not bothered about having blackberry messenger, I would definitely get an iphone. and in these days where most people have free texts, i wish i had.
The best thing about this phone is the keyboard which slides out being used with the touch screen. the two work very well together.
