Your flat out wrong buddy. I downloaded break classic when i first got my iPhone it was free. A couple days ago there was an update and decided to give it another try. They are now charging, but I was not charged again, I was able to download the update free.
Also, net news wire is still free.
I know there is a lot of misinformation on these boards, but there is no need to just make things up as you go, seriously...
Also, just to make this a somewhat on topic post, I downloaded Jaadu, and I for one am not overly impressed. I use winadmin, and I know it's a different protocol, but that's about how fast I expected the program to run. Not only is it not usable for me over 3G (because it's SO slow), but even WIFI is sluggish. Also, I have a desktop with 2 monitors and the screen won't even load. Winadmin works fine under both conditions. Again, it could be a protocol issue and not a program issue but either way, for me, it's a wasted $5.
Unfortunately it is not working as promised and advertised for all apps. Several developers have screwed users with this already. See: NetNewsWire and Break Classic. Both apps were once free, are now paid, and cannot be updated unless you paid for it.
Other apps that were once free and now paid have not had this issue. But it's clearly not an "issue" it's the developer intentionally modifying the app to screw users who were nice enough to try it when free.
