Apple long ago announced it's Bluetooth headset that pairs with the iPhone. Until recently, limited details were available for the headset and Apple was not yet taking orders for the device. Now, however, you can pre-order the headset via Apple's online store. The headset is currently estimated to ship in 2-4 weeks.
For iPhones using firmware 3.0 or higher, forwarding of SMS messages is a built in feature. To forward a text message, simply
1) view the SMS text message conversation containing the message you'd like to forward
2) tap EDIT at the top of the screen
3) check off the message(s) you'd like to forward
4) tap FORWARD at the bottom right of the screen
Though it is often sufficient in Safari, Google Maps, etc, to double-tap in order to zoom in and out - often you need to be able to control your zooming more accurately.
The instructed method of accomplishing such is to use the two fingered "pinch" motion. Pinching your fingers together zooms the display out, while pulling your pinched fingers apart zooms the display in. We've found that this motion can often be a little clumsy, especially for those of us with iPhones that are protected by screen protectors and/or cases.
Update: iOS 9 has added a dedicated search function to Safari that allows you to search web pages for specific text.
Surprisingly, there is no native "find" function in the version of Safari that comes with the iPhone.
If you are browsing a large piece of content, and need to find a particular word or section of the page quickly, this can present a serious problem.
Thankfully, you can add a search or text finding function to Safari on your iPhone with relative ease through the use of bookmarklets.
Refer to this post for more information about bookmarklets and how to add them to your iPhone.
