Hi, are there any known problems with the 5800 phones and installing applications?
Every .sis file I've tried to install has resulted in an "Expired certificate" error, but I've checked and double checked the dates on the phone and my PC, and it's not expired! It's not even close to expiring. I tried creating a new certificate valid from today, it still fails. I've tried the usual trick of changing the phone date forward and backwards with no success, except that setting it back usually produces the expected "Certificate not yet valid" error instead.
I also tried installing the same .sis on a 3rd Ed phone, which worked fine, and tried installing Y-Browser on the 5800, which also produced an "Expired certificate" error. At this point I'm pretty sure that the problem is the 5800 itself unless I've missed some extra step you have to go through to prepare an installer for 5th Edition devices.
After searching the forum I've seen a few other mentions of this problem but no actual solutions yet. Is this actually a problem with the phone software? Are there any workarounds?
