Hack

Hack has several meanings in the technology and computer science fields. It may refer to a clever or quick fix to a computer program problem, or to a clumsy or inelegant solution to a problem. The term is also used to refer to a modification of a program or device to give the user access to features that were otherwise unavailable, such as DIY circuit bending. The general media also uses this term to describe the act of illegally breaking into a computer, better described as cracking.
Crack @ Software Cracking

Software cracking is the modification of software to remove protection methods: copy prevention, trial/demo version, serial number, hardware key, date checks, CD check or software annoyances like nag screens and adware.
The distribution and use of cracked copies is illegal in almost every developed country. There have been many lawsuits over cracking software, but most have been to do with the distribution of the duplicated product rather than the process of defeating the protection, due to the difficulty of constructing legally sound proof of individual guilt in the latter instance. In the United States, the passing of the Digital Millennium Copyright Act (DMCA) legislation made software cracking, as well as the distribution of information which enables software cracking, illegal. However, the law has hardly been tested in the U.S. judiciary in cases of reverse engineering for personal use only. The European Union passed the European Union Copyright Directive in May 2001, making software copyright infringement illegal in member states once national legislation has been enacted pursuant to the directive.
To put it in a simple word ... if you didn't buy the apps but obtain it somehow and using it illegally then its a crack. U can be sued for soliciting it.
Why Pwnagetool, Quickpwn and Winpwn is not a crack? U bought the phone and its yours so u have the right to do whatever u want to it (unless u stole the phone). Apple already said that if u jailbreak (using those hacks) then you void your warranty but can't be sued.
Pwnagetool, Quickpwn and Winpwn can be cracks if Apple sold the iPhone OS as a separate entity like our Windows or Mac OS X.
Please do more research before saying a hack is the same as a crack although the line that separate the two is a fine one.
