Upon moving houses, I've been unable to access psn store since the start of FEB and won't be able to till the mid march because the phoneline/internet won't be installed till then ¬_¬

My question is: If I'm unable to get the downloads when they are up on offer, will I miss them completely? eventhough my subscription covers it?

As far as I understand it, yes you will unfortunately.  If you can find a PS3 you can use to add items to your download basket/shopping cart, you should be OK to download them when your home internet is back up and running(I think).

Yes. You have to use your PS3 connected to internet. Maybe you could use someone's wireless for just one day when all the updates go online or something.

I pick up other people's signals and even the communal one but the ps3 always refuses to actually go online with them so I have to wait until the real one starts up ¬_¬

Yes. If you can just "purchase" them but not start downloading though, you'll be fine. Once you've claimed it you're good. 

lame, accessing a connected ps3 is more difficult than I thought :D thanks anyway.
