Handy iphone tips

A few things I've discovered with my iphone:

• Use Caps lock on the keyboard
1. Make sure it's enabled it in prefs: Settings->General->keyboard
2. To use when using typing - double tap the shift key and goes blue!
• European variant letters (accents, umlaut etc) on keyboard
• Tap and hold "e", "a", etc
• Add .com or .co.uk when typing an web/email address:
• Tap and hold on the '.' key
• Go to top of any scrolled window/app:
• Tap on the very top bar (with the time in it)
• Kill any app (OS3+ only):
1. Push and hold power button till "Slide to power off" shows
2. Let go of power button
3. Push and hold 'home' button for more than 5 secs and the app dies
• Reset your iphone:
• Push and hold both the power button and home button for more than 10 secs
• Take a screen shot:
• Push home button, then click power button
