I’ve had the iPhone 4 since Friday, and have had a few days to play around with my new toy and get used to it. Before iPhone 4, I owned (and still do) an LG enV2 and an iPod Touch 2G. I had to carry both around, one in each pocket. And if you know me, I hate having things in my pocket. With iPhone 4, I get the best of both worlds. One light-weight device in my pocket.

Where shall I start? One of the killer features of iPhone 4 would have to be the retina display. This “retina display” sports a resolution of 960×640 at 326 ppi (pixels per inch). You can’t see a single pixel. Apps that haven’t been updated for the new phone show pixelated, due to the lack of updating artwork. That’s ok- it’s actually how they look on previous-generation devices. Many developers are working hard to implement new artwork for the retina display.

As far as size and weight go, they beat anything else I have tried. The iPhone 4 feels great in my hand and in my pocket. As I stated above, I hate the feeling of things in my pocket, and the iPhone 4 pretty much solves that problem. Some may complain about the flat back, but personally I like that better. It’s about what you like. It’s just my personal preference.

Backgrounds and multitasking are a great way to complement the already advanced hardware on the iPhone 4. Pandora is one of the most used app on my iPod- and now my iPhone. Before, I could never use a different app while Pandora is playing, due to the lack of multitasking. Now, I love being able to listen to my favorite radio and send a quick text. Apple always does a good job with providing nice, high-res backgrounds for use on the iPhone. Makes me feel like I can personalize the iPhone a lot more.

Overall, I have to say this is the greatest mobile device I have ever used. I prefer it over Android, but that’s me. You may have a different preference- and that’s okay.
