Recent OS updates from Verizon and Sprint seem to only be coming out for installation through desktop manager and/or wireless updates. This means that many BES users and other special cases are left with an OS they cannot download the install file for. Even Verizon is still listing OS 126.96.36.199 on their website. This OS was leaked awhile back but here it is officially.
Tom let me know that US Cellular has bucked the trend and released OS 188.8.131.52 on their website before even releasing the device. While this is not the latest OS 184.108.40.206 that Sprint is unloading through desktop manager it seems to be the latest you can download.
