Contests, contests and more contests (and did we mention all the free stuff?)

As you might have noticed, we're in full-on contest mode of late. Something about the spring air makes us want to give stuff away. Here's a quick wrap-up of what we and our sister sites have for ya. Act now, 'cause the contests are winding down:

• The iPhone Blog: It's TiPB's Birthday Bash, and Rene & Co. are having a monster giveaway. (Hey, we know some of you WinMo faithful are dabbling with an iPod Touch or – gasp! – an iPhone on the side. Happens to the best of us.) They're giving away a full-on factory unlocked 8GB iPhone 3G in your choice of 35 different color options courtesy of the awesome folks at ColorWare. And that's just the TiPB of the iceberg. Who wants free apps!?!?!?! Check out all of their contests here.
• WMExperts: We're giving away not one, but two phones. We've got an AT&T Fuze (aka the original HTC Touch Pro), as well as an HTC Touch Dual. Contest ends Monday, so get your entry in now.
• PreCentral.net: The pre-Palm Pre release contest is over, but there are still five $50 Amazon Gift Cards to be given to PreCentral.net Forum Members. How do you win one of those? Simply sign up as a member and score one "Thanked" post or Thank another user's post – in other words, it's quality, not quantity. Get the lowdown here.
• CrackBerry.com: Hey, when aren't these guys giving away something? They've got 100 themes from JC Designs and 50 copies of TweetGenius to give away. And you can bet there will be more coming up.
