Believe me, I think I must have used most mobile on the market some time or the other. Okay that's an exaggeration the does feel like it as I get through two mobiles a year. I currently use and I find and this Blackberry Pearl. If you compare the iPhone with a Blackberry Pearl the Blackberry Pearl wins hands down, though the Blackberry Pearl is for business use, I tend to use it more for both personal and business use of then I use the iPhone. It is compact and has stacks of useful features with one or two eccentric featres like the rollball and the two letters to each button making texting a bit taxing but pretty easy after a bit of practice.
I find the phone quick to start up ie within 20 seconds. On start it shows my unread emails from my business, BT and Mac accounts and text messages. Brilliant. Excellent programmes including diary, camera phone with flash, e-mail, web browsing, mp3 player, video, picture gallery alarm etc and to be honest I can't fault it. It is small enough to but my trouser pocket and walk round without an unsightly bulge. I must admit I'm not into bulky phones.
I note that quite a few people do not seem to like this phone but I work on the basis that you need to read the manual, learn the features and have a phone for at least a few months then make a decision. I think I am justified in giving this phone a rave review and I am currently due upgrade to my mobile and I have decided not to upgrade my iPhone to the new version but I will certainly consider upgrading my Blackberry to the next level.
