Oh auto correct, how we all do loathe thee.

A couple of months ago I walked you through a jailbreak tweak entitled ManualCorrect — a tweak that aimed to tame the iPhone’s native auto correct and make it functional.

The tweak was met by rave reviews by yours truly, and even garnered a few votes on Nick’s Top Five Jailbreak Apps post.

Now a new version of the tweak — ManualCorrect Pro — has been unveiled that seeks to further subdue the iPhone’s nefarious auto correction; but is it worth paying for?

In the free version of the tweak, there were no options to configure in the Settings.app. The Pro version on the other hand, allows you to configure several options to finely tune your correction preferences.

There’s an overall kill switch to enable or disable a tweak; automatic brownie points in my book, and there are options to correct casing and punctuation.

The biggest new feature that ManualCorrect Pro offers over its predecessor is the option to add your own manual corrections.

This means that whenever I type the words “Playbook” I can auto correct it into “Lame.” Blackberry connoisseurs can do the math on that one.

Having the ability to add your own manual corrections caters to power users, and those of you who’s fingers get a lot of mileage on the iPhone’s keyboard will be indebted to the developer for this handy option.

The one thing I noticed that I didn’t particularly like about the manual corrections is that you can’t add phrases, but that might be something that will see the light of day with a future update.

As it stands, the original ManualCorrect was already an extremely competent alternative to the anger inducing iPhone auto correct; the Pro version is just the icing on the cake.

Is it worth a dollar? Certainly, especially if you do a lot of typing on your iPhone. The developer even tossed in a handy SBSettings toggle to quickly enable and disable the tweak.

ManualCorrect Pro is available for $0.99 on Cydia for those of you with jailbroken iPhones.

Have you tried it out yet? What do you think?
