Five apps that solve common iPhone problems

The iPhone famously solves many of life's little problems--you can't decide where to eat, you've got nothing to read, you need to update your Facebook status right now--but who's going to solve the iPhone's problems?

For instance, maybe it's low on storage. Or it's having trouble connecting to a Starbucks hot spot. Here's a list of five common iPhone ailments and the apps that aim to cure them.

• You're running out of storage. Apple may have a 32GB iPhone waiting in the wings, but how does that help you and your storage-strapped model now? Here's one radical idea: delete all your music. Then install Simplify Media, a $3.99 app that streams your entire music library from your Windows, Mac, or Linux PC. I've been test-driving the app for a few days and it works like a charm. Just think of how much space you'll free up for apps, videos, photos, and the like.
• You're texting your way to the poorhouse. Tired of dropping an extra $20 per month for unlimited texting? How about a one-time fee of $5.99 instead? That's the price of Textfree Unlimited, which, true to its name, lets you send and receive an unlimited number of text messages. It's not perfect--you need to enable "push" mail if you want new-message notifications--but it'll definitely save you money.
• There's no way to check your SMS count. Prefer to stick with old-school texting? It would be nice if you could see how many messages you have left for the month. Pageonce just took the wraps off Cell Minute Tracker, a 99-cent app that shows not only your SMS usage, but also your AT&T account balance, rollover minutes, and more. (You can even pay your bill.)

• There's no to-do list. Third-party apps to the rescue! Chapura's KeyTasks provides robust task management, and it syncs with Outlook. (But $9.99? Ouch!) Appigo's Todo offers iCal syncing for Mac users for an equally ouchy $9.99. If you'd rather sync your tasks to the Web, try Remember The Milk. The app's free, but you need a $25/year pro account.
• Connecting to Starbucks' Wi-Fi is a hassle. Oh, the hoops you must jump to tap a Starbucks Wi-Fi network. For a mere 99 cents, Easy Wi-Fi lives up to its name, making AT&T hot-spot connections a one-tap affair. No monkeying around with text messages and all that: you'll be online faster than you'll be sipping your latte.
