Microsoft Continues To Bleed Mobile Market Share, Despite WP7
Microsoft will soon be launching an approved Windows Phone unlocking service as part of ChevronWP7 Labs. This allows developers to immediately launch apps on the Windows Phone 7 platform, without waiting for official Microsoft approval. This also allows users to run these “homebrew” apps on their Windows phones.
The ChevronWP7 service will require developers to pay a small fee via PayPal to offset costs, but it should be much less than the $99 annual fee to release apps in the WP7 App Hub.
ChevronWP7 comes with Microsoft’s full blessing and support, which means homebrew apps shouldn’t break in future Windows Phone updates. Microsoft should be commended for opening up Windows Phone 7. This leaves Apple as the only smartphone developer that does not officially support homebrew apps.
