I’ve seen a huge spike in traffic on my site searching for iOS lost contacts. We now have 6 different solutions to restore your contacts.
Thought I’d post something specifically regarding iOS 5, and some solutions that are out there. Personally I had no problems upgrading, and think losing contacts may just be because the initial “sync” hasn’t gone through yet (remember an iOS upgrade resets your phone to base iOS 5, then imports your information after).
I just updated this site to WordPress 3.1, and it took the site down. The automatic updated failed to update the site, and left the site in a permanent “500 Internal Server Error”.
How to fix any failed WordPress core Update (3.1 included)
Understand that one beautify of WordPress is that the core software is entirely separate from any customizations (if done right). This means as long as you leave 2 items alone, you can replace your entire install.
