Well I bought the 16G Iphone 3GS on Friday and I like it very much. There are a lot of apps for free and are quite useful. Many of the other apps are only 99¢. I already had unlimited Internet and texting on my old phone so no additional charge there.
I was debating between the Blackberry and Iphone. I did not like the trackball on the BB and the only advantage of the BB was I could load MS Office docs in it, but I didn't do that with my Motorola Q and I wanted a phone that would be better on the Internet. The 3GS is very fast loading web pages.
One app that is free and I find useful is AroundMe. It gives you locations of banks, shops, restaurants, gas stations, etc., directions how to get there from your present location and the phone number. The YP app is great also, no need for a phone book. I love the voice dialing, no need to assign voice tags. It will call all the numbers in your contacts by name and which phone you want to dial, their mobile, home, office, etc. And the voice Google is awesome. No need to type in what you are searching for, just speak it. I am surprised how well the IP's voice recognition is.
I did buy a couple of apps. 99¢ for the Registered Sex Offenders. That one will find them by either using your present location or by typing in an address. I have around 50 within a 2 mile radius from my home, but none in my subdivision. It even shows the offender's picture and what they were convicted for. A $1.99 app is the Handy Carpenter. It turns the IP into a level, plumb bob, ruler and protractor. I used it to measure a distance of 11⅞ inches and it was accurate to within ⅛ inch of it. It will be handy to measure the width of a gate if I don't have a tape with me.
I also loaded working pictures in it and pictures are displayed much better than my old phone and you can actually see detail without straining the eyes. I could show potential customers some of my work without carry around a photo album.
I think it is a great phone with a lot of useful apps. Right now I am happy I got it. I do have a 30 day trial period to take it back if I change my mind, but I don't think I will. Battery life isn't very good when using it. It does need to be charged every day, but Apple will replace the battery if it starts to fail within a year. $69 to extend the warranty on the whole phone for an additional year. I may get that, but I have a year to decide.
