Make your own ringtone: Don't settle with the ringtones provided by Apple and you need not pay your carrier for more of them. As the name suggests, the free Ringtone Maker app lets you take a clip from your favorite songs and make ringtones out of them in seconds.
Feel and see when people call: Apple has added a number of accessibility features to iOS 5, specifically designed to assist those with hearing, vision, mobility and other disabilities. For example, those who are hearing impaired might opt to have the LED flash when a call comes in. If you're seeing impaired, you could set a unique vibration pattern for different people in your Contacts, so you know who's calling.
Find your lost iPhone: As long as you sign up in advance, the free Find My iPhone app will help you locate your device on a map (on your computer or other iOS device). You can display a message or initiate a loud ring (in case it's under the cushions), or remotely lock or wipe its data.
Save photos in Safari: You're surfing the web in Safari and stumble upon a photo you'd like to save. Simply press and hold on a photo when on a website and you'll be prompted with a menu asked if you'd like to "Save Image." Once the photo is saved, you can view it offline, email it or set it as wallpaper.
Take an iPhone screen grab: On a related note, if you want to take a screenshot of a website or application, press down on the Home button and tap the Sleep button. You'll hear the camera click, see a white flash and the screenshot will be saved to your Camera Roll.
Get new sounds: It's been a long time coming, but Apple has added the ability to select custom tones for incoming text messages, new emails, voicemails, tweets, calendar alerts, reminders and more. You can select something you like from within the Sounds menu. You'll also notice you can scroll to the top of this list of sounds and you'll see a "Buy More Tones" option, which takes you to iTunes.
Zip to the top of the page: In Mail, Safari, Contacts and other apps, simply tap the status bar at the top of the screen — the area that displays time, battery and cell bars — to jump back to the top quickly.
Prolong your battery: Speaking of the battery, here's how to squeeze more life out of your iPhonebetween charges. Turn down the brightness of your screen, turn off wireless radios you don't use (such as GPS, Wi-Fi or Bluetooth) and reduce the number of apps with info you have "pushed" to your phone. Also, make sure you lock it before putting in your pocket, purse or backpack or else it could turn on and drain the battery.
Spread out the keyboard for easier typing: Here's a tip for iPad users: If you like typing while holding the tablet, rather than stretch your fingers or thumbs for those middle letters like G, H, Y or B, you can drag the keyboard to each side of the screen to separate it into two, allowing you to easily type while holding it.
Learn some gestures: Close any app ridiculously fast by putting your four fingers and thumb stretched on the screen and pinch inwards. Sweet! You can also magnify what's on your iPhone screen with a three-finger tap. You'll first need to go to Settings, General, Accessibility, and select the various gestures options here.
Create an "app" out of a website you visit often: To add a website to your Home screen, just visit the webpage in Safari and at the top of the screen, tap the Go To icon and select "Add to Home Screen."
Create a music playlist on the fly: You no longer need a computer to create a playlist. In the Music app, tap Playlists, then select Add Playlist and give it a name ("Marc's Workout Mix"). Now, tap any song (or video) to add it to the playlist. You can add individual songs, entire albums, or all songs by a particular artist.
Don't waste your day deleting messages individually: You can delete unwanted emails en masse rather than deleting one at a time. In your Inbox, simply click the Edit button and check off the emails you want to delete with your finger and then choose Delete.
Keep track of your texting limits: If you don't have the best texting plan and don't want to unnecessarily pay to send more texts than you need, here's a tip to turn on the character count in the Messages app. Enable this in the Settings>Message option to keep an eye on your word count. Usually, your one text becomes two after 160 characters.
Mirror your iPhone with your TV: If you own an Apple TV, you can instantly and wirelessly share exactly what's on your iPhone 4S or second- and third-generation iPad with your HDTV, connected to an Apple TV — such as games, apps or videos. Simply double-tap the Home button, swipe all the way to the right and select AirPlay Mirroring.
