Oh, and if you have 2 iPhones (you and your wife or girlfriend or whatever) - register them both using the same iTunes account & you can use the same Apps on both iPhones. Example - I paid for Monkeyball & downloaded it on my iPhone & then my wife DL'd it & installed it on hers for free. I think you can put them on up to 5 devices under the same account.  

Repeat songs or playlist -

When playing a song in the iPod click on the the album art one time while holding the iPhone vertically (yes it has to be vertically). A timeline will appear at the top. Click on the to the left to repeat a playlist. Click the icon a second time and a "1" will appear meaning it'll repeat a single song. You can now use the timeline to move to different points in the song instead of holding the back and forward buttons on the bottom.

1. Screenshot- Hold Home button & press top/sleep button. Screen will flash & picture saves to Camera Roll.

2. Save pictures in email & on the web - hold your finger on the picture & it will ask you if you want to save it. Also saves to your Camera Roll.

3. When typing a web address, hold the ".com" key down & you will also get .net, .edu, .org to choose from.

4. In Settings, Under Mail, Contact, Calendars, you can now import SIM contacts...

5. Some AppStore programs hide their settings in the iPhone Settings menu. It took me awhile to figure out how to change AIM's Username/Password, until I found the AIM Settings hiding there... So far I've also seen Shazam's & Save Benji's settings there as well...

Wow, thanks!
