Tired of all those apps that you no longer use taking up space on your computer? If you have apps that you no longer want to use on your iPhone or iPad, you may have tried to figure out how to delete them permanently from your Mac, Macbook, or other computer. And you may have been frustrated to see them popping right back up in iTunes, and taking up space.

“iPhone text messages won’t stay deleted and keep coming back,” complains one user. “How can I permanently delete iMessage SMS messages?” asks another. It seems that no matter what you do to delete those text messages, they keep coming back! Here’s how to delete text messages and text message threads on your iPhone permanently, so that they don’t reappear.

Dropbox, the cloud-based file storage service, has 500 million users. And an appreciable number of those Dropbox users can’t figure out how to delete files, let alone how to delete files permanently, on Dropbox. In part that’s because despite being nearly 10 years old, Dropbox’ user interface (“UI”) is still stuck in 1998, and in part because, well, the “how to delete” mechanism is buried and poorly documented.

One of the most frustrating things about the Tmobile G2 – an otherwise fantastic smartphone – is the lack of any settings to control the keyboard backlight: you can’t have your keyboard backlight always on, even if you want to. The light sensor that controls the keyboard back light on the G2 is crazy-sensitive to ambient light, and so one often finds oneself trying to type blind, because the keys are not lit up, and it’s too dark to easily see the keyboard. If you want to keep your keyboard backlight on permanently, well, there is no setting to do that. But there is a way to do it, and we tell you how (with pictures!) First you need to know exactly where is the G2 light sensor.
