Last week, I took the plunge and upgraded my iPhone up to 2.1. I was waiting a bit to let the “pwnage” tool work itself out and let the bugs get worked out of the 2.0 firmware by Apple. However, when I found out there was an iPhone app for the Evernote service, I just had to upgrade.
To do it, I more or less followed these instructions here.
My only hiccup happened when I tried to install the new patched firmware to my phone via iTunes 8 on my Macbook. I tried three or four times and got some scary “Unknown Error: -2005″ and “Unknown Error: -1612″ messages with my blankscreened iPhone. Happily it was never bricked, I just needed to hold the power button down for about 15 seconds.
Just a side note, I’ve noticed that Macs an interesting philosophy for errors in their apps: either show no indication that something went wrong, or pop up a cryptic useless message. I much prefer the Linux world of logging everything to a log file somewhere. You may not understand it, but at least you have something to paste into Google!
Anyway, the web wasn’t much help, while these errors are sometimes cleared up by switching USB ports or taking out the SIM card, no one had any consistant explanations or solutions. I figured that the problem might be my USB ports when I recalled that I had not been able to get my external HD to work on one of them earlier in the week.
So, I put all the software on my iMac at home, tried again and “ta-da” it worked first time! It took around 30 minutes to finish all the installation and re-syncing, and within an hour or two I was being more productive with Evernote and less productive with Spore: Origins.
Good luck!
