Thanks to author crash-x, there is a new app called 3G Unrestrictor that will do what VoIPOver3G and Tricker ThreeG have done before - allow you to use Wi-Fi only apps on your iPhone while you’re on the 3G network.  Rejoice!

The options for push email on the iPhone are 3 : MobileMe, Yahoo Mail, and Microsoft Exchange.  MobileMe seems like a nice service, but I already have my trusty Gmail account (using a hosted domain) and I’m not too interested in migrating.  I had been forwarding all new messages from my Gmail account over to a Yahoo account for the push-like service, but now there’s something new out there that is working pretty well - NuevaSync.

UPDATE: crash-x has release 3G Unrestrictor to allow wi-fi only apps to run over the 3G network.  Read more here.

So I now have my shiny 3GS safely jailbroken using the Iphone Dev Team’s latest tools, and happily running Intelliscreen and Elert, along with my other favorite JB apps like SBSettings.  But I am missing one of the best hacks from the the OS 2.0 days…Tricker ThreeG and VoipOver3G to allow SlingPlayer on my iPhone 3GS.

UPDATE 2: This no longer works on OS 3.0, specifically with an iPhone 3GS.  Read more below in the comments in this article, and this post.

UPDATE: As reader John Michael points out in the comments below, Jordan Clark has released Tricker ThreeG in Cydia, which is an alternative to using VoIPover3G for those who don’t wish to modify the VoIPover3G file.  Tricker ThreeG is a nice one step solution to get SlingPlayer working on 3G.  (Thanks John and Jordan!)

Jailbreakers rejoice!  SlingPlayer works over 3G using VoIPover3G!  Read on for our first impressions of the app and how quickly you realize that 3G is a must for this app.

Engadget is reporting that SlingPlayer is finally due for the iPhone Wednesday morning, May 13, and the have a few first impressions.  There appear to be 2 huge caveats from the start:

1. It’s $29.99
2. WiFi only - it won’t work over 3G or Edge

Today’s Woot deal is a Hava Titanium HD with the Wifi dongle for only $80!  That’s is an excellent deal - I got my Platinum HD (no Wifi) for $80 on sale at Amazon months ago, and now even that is up over $100.  Grab one while you can to get some iPhone TV streaming!

The long-awaited Slingbox Slingplayer application for the iPhone has been submitted to the Apple’s AppStore, according to Slingbox’s website.  Applied Gadgetry won’t be able to resist temptation and put  up the new player head to head with our current Hava/Orb setup.  It’s not exactly a fair comparison, but it will have to do until Hava can get their native player out as well - hopefully for the end of the second quarter.

The big question about the Slingbox app other than the normal interface, streaming quality, and overall responsiveness - how much is this thing going to cost? 

Anyone watching “24″ on Fox probably can’t help but giggle a little whenever the show talks about the magical “CIP device” .  For those of you who don’t watch, it is a tiny firewall-destroying device that can tunnel through those internet tubes and allow its user to hack into everything from any air traffic control tower in America down to water plants, and presumably, your grandfather’s pacemaker.  Yes, it’s the ultimate in “applied gadgetry”, and lucky for us, it’s also the ultimate “plot device”.

What you will need

1. A PC (Vista, XP Service Pack 2, or XP Media Center Edition) with a TV Tuner installed. I’ll use a Hava Platinum HD Media Streamer as a “wireless” TV Tuner.
2. Orb installed on a PC (free, link)
3. OrbLive installed on your iPhone ($9.99, link opens AppStore)

At CES, Hava released a statement saying that they will release a native iPhone application to enable users to stream their TV goodness directly to their iPhone.  Likely a direct response to SlingMedia’s recent announcements, it gears up iPhone users who want several streaming options for a choice.  Until then, you can use Hava combined with Orb for a nice stopgap solution.
