Again, that is in the real world. Shadowrun does not work that way. See, even you have a hard time getting out of the real world mindset... 
Purge your mind of the real world constraints and paradigms in regards to computers and you will be set free...

This is actually a commonly offered view, but in practice a very bad one for games.
Why? Because if you're trying to present something in a game as "It's a computer." then you must expect players to deal with it as one, and get angry when it's disallowed. If you're trying to present something as "It's not a computer." then you must expect them to use computers for things computers are good at. If you're trying to say "There are no computers, and this is the closest approximation so deal with it." then suspension of disbelief flies out of the window precisely because you're challenging the very underlying concepts of the milieu.
The game source materials explicitly say that commlinks are computers and that the matrix as a whole is the network environment. Blanket responses to the effect of "Yeah, all those computer things which computers are great at and we use computers for all the time and have for decades and decades in the real world just suddenly don't work because it's not in the rulebook." don't fly. Not at my table, not at any table I've been at.
Get it? It's not the `real world constraints' or the `real world mindset' which matters except in the presentation and the player expectations - and there it all matters deeply, and irretrievably. Shadowrun (to refer to another thread) doesn't have explicit animal husbandry rules either - that doesn't mean animals don't breed.
It would matter a lot less if the game source materials provided a whole new fundamental set of principles on which electronics (or the game equivalent) functions - but it doesn't. Not even a little bit. It just offers gaming abstractions, and describes VR as being an efficient way, within the game, and within the VR metaphor, for interacting with computers. It even makes explicit references to where the VR interface is not an adequate metaphor for what is happening under the skin (the Fastjack fiction snippet in the anniversary rules also make reference to this, as source material example) and reflects the fact that you are loading programs onto an electronic device.
So go ahead - call it house rules, call it gamebreaking, call it what you like, but at my table, commlinks are computers and ingenuity in their use, recognising that what you are using is a data processing device and using that information to buttress your in-game decisions, will be permitted. You'll roll for your electronics and hacking skills - of course you will. But if you have the skills, the technology has the flexibility.
To develop the point about the milieu, it even goes further - Shadowrun juxtaposes very well the rise of technology and the rise of what people generally have regarded as nontechnological or even antitechnological, in parallel, very well. The social questions which are raised, the implications for the elite nature of magic, and the democratising nature of technology, make for a great situation to examine. Reducing the high technology of the system to just another set of inflexible buttontwiddles eviscerates this aspect of the milieu, to the loss of the game's philosophical depth. All right in a beer-and-pretzels one-shot game, but lousy in an ongoing campaign.
