QuickTip – There is a way to quickly put your iPhone or iPod Touch into “lock” mode without waiting for it to auto-lock on it’s own. To do so, just quickly press the power button (that is the button on the top of your device) one time. Do not hold the power button down (this would turn your device off) instead just give it a quick tap and voilà your iPhone or iPod Touch will lock.

In conjunction with that, you can also use your power button to bring your iPhone or iPod Touch out of sleep/lock mode. Just give it another quick tap and it will wake-up. It is basically the same as pressing your Home Button while your iPhone is in sleep/lock mode.

Doug acutally always uses this method to lock his iPhone…he turns off his auto-lock and just does it manually (as described above). I use this method a lot too but, I have to leave the auto-lock feature on because sometime I set down my iPhone and forget to lock it and my battery would totally be dead!

QuickTip – When using Safari, it keeps track of your browsing History (similar to a Mac or PC). This is a nice feature for those times when you would like to go back to a website you were at a few days ago but cannot remember the site’s url. To see your Safari history, while in Safari, select the icon on the lower menu bar that looks like a book. You will then see an option titled History. When selected, it will display your browsing history for the current day as well as the last five days. To view one of the website’s in you history, just tap on it.

While in your history, you will also notice that there is a Clear option on the lower menu bar. You can choose to clear all your history or you can tap on a certain date and then clear the history just for that day. This is a quick and easy way to erase your Safari history. See screenshots below.

CheckPlease is the only free tip calculator/bill splitting application in the App Store (as of right now). This type of application is one that I like to have available on my iPhone. It is so much easier to type in a few numbers and have it spit out the totals than it is to sit around trying to guesstimate what everyone’s share of the bill is! When you open CheckPlease, you can enter the Check Total and the Tax Amount (in dollars). To enter a number just tap in the box in which you would like to enter the number and a keyboard will pop-up. When you are done typing in the amount, select Done in the lower right corner. It will automatically generate your Subtotal.

To figure out the tip amount, slide the star until it is where you would like it on the tip% bar. The tip percentage options range from 0% to 30%. Once you have the tip% where you would like it, the application will automatically generate your Grand Total. You can then choose how many people you would like to split the bill between by moving the smiley face along the bar. The bar starts at 1 and goes to 20. Once you are finished, how much each person owes is displayed at the bottom of the screen in the $ per Person option. You will also notice a i icon in the lower right corner of the app. This will bring you to the Settings where you have the options to set a default Tax % and Tip Rate. I did take a few times using the app before I was totally comfortable with it. But, it does what it is supposed to do and it does it for free.

Note: You will need to have Jiggy Runtime installed before you can install Tipper.
