Sprint will start limiting mobile hotspot use, when a phone is turned into a Wi-Fi gateway, to 5 GB for both current and new subscribers starting 2 October 2011. Additional gigabytes cost $50 each, billed by the megabyte. Sprint is the last U.S. carrier to offer true unlimited 3G service, which remains available for on-phone data usage — for now! follow link
Copy Before Submitting Web Forms
Filling in Web forms (like the one used to submit this tip) can be a bit of a gamble - you put in your pearls of wisdom, perhaps only to lose them all if the Web page flakes out or the browser crashes. Instead of losing all your text, "save" it by pressing Command-A to select all and then Command-C to copy the selected text to the clipboard. Do this periodically as you type and before you click Submit, and you may "save" yourself from a lot of frustration. It takes just a second to do, and the first time you need to rely on it to paste back in lost text, you'll feel smart.
