Well, the developers of instagr.am (who just nabbed $7m) haven’t bothered with other mobile platforms as yet.

Conventional wisdom is that you do iPhone first. Then 6 months later, you think about Android. Then about a year later — and only after you’ve been lobbied hard by other platform owners — do you bother launching a RIM/Nokia/WP7/Bada version.

This is fine as long as the market plays along.

Instagr.am has some competition on Windows Phone 7 as MobileCrunch reports:

After growing tired of waiting for any of these picture sharing services to come to them, they built one of their own: bubblegum. And yes, it has the silly filters.

Launching later today (on Windows Phone 7 only, for now), Bubblegum was built by Sriram Krishnan (Program Manager for Microsoft’s Windows Azure) and Aarthi Ramamurthy (Program Manager for Microsoft’s XNA) in their nights and weekends off. Bonus trivia, mainly because it’s kind of cool: Sriram and Aarthi aren’t just partners in this endeavor — they’re also partners in love. In other words, they’re married.

Yup, another team of developers has taken a look at instagr.am and thought, ‘nice’. Boom. The app is live.

This is potentially hugely dangerous for the original developers who, having cracked iPhone could well be a little too late to the party on other platforms.

The jury is most definitely out with Bubblegum, the WP7 instagr.am competitor, but if you’re using a device on WP7, chances are you’ll want to check out Bubblegum.

Now and again I’ve been hunting through BlackBerry’s App World to see if any bright spark has released an instagr.am clone for that platform. Not yet it seems, but it’s only a matter of time.

I wonder how long it will be before developers begin releasing on all platforms simultaneously to prevent/reduce the effects of this kind of approach?

And it is.

We’re live. And the mobile industry is changed for good.

Finally you can deploy an application, easily, for Nokia customers. It used to be an absolutely torturous process — now, the discovery is much, much improved.

Similarly, if you’d like, for example, some Star Trek wallpapers on your Nokia, you can now click-click and be done. No more arsing around. Fantastic.

Here’s a screenshot from the desktop:

The store is wholly sluggish this morning because the whole world and his dog is checking in, downloading and playing around.

You can already see just how massively successful the store is going to be. I’m looking at a ‘futuristic‘ Star Trek Ringtone — that’s priced free. On the right hand side I’ve got these options:

And it’s free? I’ll have that.

As for billing, well your operator will take care of your purchase processing in Australia, Britain, Germany, Ireland, Italy, Russia, Singapore and Spain. So it’s just one click to buy. Magic from a mobile developer standpoint. I’m going to give it a try in a few minutes.

And for revenue sharing? Well 30% revenue share is fast becoming standard across the app store world and Nokia is keeping to that — there are a few questions over exactly how the splits will work but I’m sure we’ll see some further clarification on this soon.

Here’s what store.ovi.com looks like on my Nokia N82 browser:

I’ll download the app and take you on a tour shortly.

For now… the Ovi Store is live… let’s see what everyone thinks about it!
