After I broke details on BREW Revision 1's easy workaround on extending demos or turning them into full apps onto HoFo, I should have suspected Revision 2 would incorporate encryption and/or digital signatures into the MIF files to prevent further tampering.

However, that doesn't prevent anyone from taking a "snapshot" of their MIF files for future reference.

I remember reading a post somewhere here that one could download a 5-minute demo of an app or game, then after it downloads, it asks if you want to run it now, you click the CLEAR button instead of choosing an option, and you can "download" it again. Only, this time, it increases the time limit by the same amount. Doing this a few times could give you a cumulative 60 minute demo, or more, for example.

That's where Bitpim comes in. After you've gathered enough minutes to play on the crapper or in a given session, don't run the app or game. Instead, connect your phone to Bitpim and download the appropriate MIF file to your PC and tuck it away for safekeeping.

Now, enjoy the demo for a bit, and when you've run low or out of remaining time, just overwrite the same MIF file and you'll be back to when you first downloaded the app.

Until someone comes up with a way to decipher the encrypted MIF file, this'll have to do for now.

Very cool discovery, but do you know if there is a limmit to the amount of free minutes? Not that an hour isnt enough for me

edit: what does your sig mean?

i cant do this on my v710

after i DL it, the 'free trial' dissappears from the list of options


of the 2 games that even have free trial

I tried it and it did work! I screwed up on by accidentally choosing "No" and it went back to the list of apps. Just like he wrote, you must press the CLR button immediately after the program downloads, and it's like you press the Back button while surfing - it seems to load the cached page allowing you to choose the same option again.

Once you've downloaded the trial of that particular GIN app, the ability to choose the free 5-minute demo is gone for good.

Cool find, though, thanks!

thats cool. i did this trick with moviegoer and it now expires on jan 17 2005. and some demos whent up to 80 min. do you know if it counts as a download everytime you do it. i also found out that if you mess up on doing this. just erase the app and then delete the prefs.dat file and all the demos come back that are not loaded to your phone

When I do this, instead of downloading it again, it just asks if I want to run it. Am I doing something wrong or is something different?

EDIT: Nevermind - it adds minutes almost instantaneously.

where do i find and how do i delete the prefs.dat file

using bitpim, you need to navigate to /brew/prefs.dat

what if i have already payed for a particuar app, will deleting this file cause problems with that?

as long as you keep the mif, probably not

however, i can't say for sure

has anyone tried it with ringtoes?
If u did that do u think that you would get more credits
everytime u did that? or would they charge u?

I have almost every ringertone off of ModTonez.
If someone wants to host them....

It depends, I just got hosting with quite a bit of bandwidth; just cause it was a helluva deal ^_^

Sizes please?

I just did this for roughly 10 programs, and i have over 50 minutes on each. yet when i go into the GIN menu to open each one it will not open it and it tlls me that this is ademo version, and to buy it now click ok. Yet in the setting, it says 50+ minutes for each program. Any help will be appreciated!

EDIT: NVMD, im a *******. I didnt realize that you had to hit the down arrow at that screen.

Also, does anyone care to post a list of all apps with an available demo.
