The USB connectivity is what drives people crazy, you can just about pluck open the cap but it doesn't come with a cable - little tip - plenty of MP3 players use the same USB which is very useful.
If you use your phone quite often throughout the day, only buy this phone if you are able to charge it at LEAST once every 2 days because the battery is not great.
The phone memory is not great either but cards are easy to get and are often included.
Besides this, the only other thing to say is that you won't regret buying a Nokia 6300. It functions perfectly, it looks great, its strong and the images quality is great.
There is no better phone at a cheaper price - highly recomended
