When the time comes to update our phones with Android 2.1 or whatever, I know we need to back up our contacts and so on, if we don;t want to lose them, but what happens to apps we've installed? I have, for example, installed a Japanese dictionary on my phone, and really don't want to have to buy it again when I update my phone.
Is it possible to transfer everything to the memory card to keep it safe, or would that not be enough to preserve the stuff we've bought / installed?
Did you get the dictionary right from the Market? If so, when you update in the future, as long as you sign back into the market with the same Google Account, you should be able to download it again without issue.
If you bought it from some external site, you'll have to contact that site. Considering updates/resets are fairly common across the board with Android I imagine they have some sort of policy regarding re-installing applcations.
Yes, everything I have put on my phone is from the Android Market, through the phone. I notice that, when I go to the Market from the phone, it shwos the things I have downloaded, so I guess I just need to go to that and reload the apps.
