There is growing evidence that this software is not capable of matching it claims.

I ran the app through a debugger watching its every step. There's a couple of key points. Firstly, as already mentioned, this is a MIDP app and doesn't utilize any of the RIM CLDC apis. That in itself is already enough to guarantee that what they claim is impossible. The second point, which is probably the most important to understand, it that 3rd party applications have absolutely no control over how the device actually connects to the network besides being able to specify the network route and security settings at a very high level. Even then, you can only affect your OWN application in this manner.
The app does absolutely NOTHING related to network operations. If you see any network gains after running this app, I promise you, those are perceived, not real.
I'm only going to say this once for Daniel and for everyone else that is working with him. What you are doing is criminal, and you need to stop. You are taking advantage of technical ignorance and making a profit off an application that does nothing.
I would hope that organizations like mobihand and crackberry would remove this application from their storefronts immediately.
I also had a look at MemoryUp. All that application does is call System.gc() periodically. Again, there are a couple reasons why this is useless. Firstly, if the system is running low on resources, it will perform a full GC anyways. Second, calling System.gc() does not guarantee anything. The VM will determine when to do the garbage collection. And last but not least, the VM has a much better idea of what is going on with memory than any 3rd party app ever could, and the VM will employ some smart heuristics to do garbage collections at the appropriate times.
I'm actually shocked that MemoryUp made it onto app world given the talk Mike Kirkup (Technical lead of the BlackBerry Alliance program at Research In Motion) gave at the developer conference last Autumn about how 3rd party apps can't really affect memory at all.
Maybe they should be notified of the mistake... |
Use your trail period to check it out with a stopwatch, before you spend the money. No refunds.
