I have just recently started using all of the features of this phone. I was tempted to get one after I saw my friend's V300 with T-Mobile. I have AT&T Service and this phone was only unlocked to Cingular Wireless so when i bought it (second hand) it had to be unlocked by a 3rd party company for $25. Other than that, this phone has been amazing. The data cable is great for getting MP3 ringtones, keeping up with my Outlook data and also sending pictures I take to my computer. All of the memory on this phone is great for storing pictures (the camera has great quality) as well as MP3 files, contacts and Microsoft Outlook calandar data. I highly reccomend this phone!
