Chat for GTalk is a Google Talk client for the iPhone. The appearance is highly customizable and comes with three themes.

I’m not a big Google Talk user, but if I was, the UI and themes for this app would suck me in.

Details, screenshots, and video after the break.

Chat for Gtalk offers a unique ability to completely change the appearance of chat window, contact list, fonts and background colors of the app. The first version of Chat for Gtalk introduces three fancy themes: Paper, Racing and Simple White.

• Chat with your GTalk / Google+ friends with the niftiest messenger on the App Store
• Give your friends the idea of what you’re up to with customizable status messages
• Cloud-based Chat History with easy access to any conversation you had earlier
• Send pictures on the go right from the app
• Push notifications will deliver incoming messages even if you are not in Chat for GTalk
• Integrated Web browser: open links from the conversations without leaving the app
• Supports both landscape and portrait orientations for your convenience
• Splendid graphic emoticons

Chat for GTalk is available on the iPhone for $0.99.

When Google opens their wallet, big buyouts follow, and this time it’s iPhone/mobile advertising company AdMob for $750 million, and VoIP startup Gizmo5 for about $30 million.

AdMob is an obvious choice for Google, as it’s built mobile and in-app advertising (especially on the iPhone) into a $100 million a year business, enough to get Brin and Page personally involved in the courtship. Says TechCrunch:

Google is gunning hard to dominate mobile Web advertising and AdMob has an early foothold in the display side. [...] Google’s purchase price tells us it thinks the opportunity for mobile display ads is in the billions of dollars, at the very least.

Gizmo5, rather than advertising, could help round out Google’s services portfolio. Again, TechCrunch has the details:

Google Talk allows voice calls between users but has no PSTN link to allow incoming or outbound calls to real phones. Gizmo5 does this well already. [...] And Google Voice is a great VoIP and phone identity service, but they have no endpoint for calls. Gizmo5, which by the way already integrates with Google Voice, is a soft phone end point for Google phone users.

Of course, Apple will have to stop considering/reverse the rejection of Google Voice, or Google will have to deliver that killer web app version, before iPhone users benefit from that…

Folks who’ve transitioned over from Windows Mobile (or BlackBerry) to the iPhone (or folks who, like me, are dual-wielding) take heed: one of our favorite IM apps from those other platforms has finally made its way into the App Store. It’s Palringo (iTunes Link) and it’s free. Palringo is an instant messenger app that’s able to talk to AIM, MSN, Yahoo, Google Talk, etc. It will also let you send media files (like photos). There is one downside — you do need to set up a Palringo account to get it all going, but for now at least, if you want multi-client IM, Palringo’s your best option.

That’s good stuff, but the better stuff is coming: Palringo’s custom ‘Vocal IM,’ which is somewhere between sending audio files and VOIP chat. We’re also hoping that Palringo will be able to add background notifications when the iPhone supports it.

I’m downloading now, but I tell ya, I’m excited for this app. Seems like an excellent idea for a lightning review, don’t it?

Although it seems pretty clear that there’s going to be a native chat client for the iPhone 2.0 that will support Google Talk (with background alerts to boot!), there may be those that have a religious injunction against installing applications. There may also be those who don’t intend to upgrade because they don’t want to mess around with losing either their unlocked or jailbroken status. Whatever your reason for not using a native app, Google’s got ya covered with an all new interface for Google Talk, fully optimized for Mobile Safari.

It’s cool and all, but the moment you navigate away (or close) from Safari your status is set to unavailable. On the bright side, though, if you’re a Google-holic it integrates nicely with your contacts and otherwise works exactly how you’d expect a Google Talk Client (inside a web browser) to work.

Just point your iPhone to http://www.google.com/talk to give it a shot.
