The blasting heat of summer may be just beginning for most of us, but that's not stopping Microsoft from already pursuing the build up of its app development for Windows Phone 7. As we closely approach the target launch date for Microsoft's next generation mobile platform, the availability of quality apps from the onset can hinge on its overall success. That's why they're starting early by throwing a contest where they are looking for ideas on a great app for their platform with a grand prize winner receiving $5,000 for their idea and a brand spanking new Windows Phone 7 handset. So how do you apply for this? Anyone can simply throw in their suggestion by recording a maximum 90 second clip or write a maximum 1,000 word listing. Ultimately, the winner will have their app submission be created and released for free by Microsoft. Although there can just be one winner at the end of all of this, thankfully Microsoft will also be giving out 16GB ZuneHDs to the next four runner-ups.
