To me it is obvious that the Iranians have just imported weapons to Assad using the 18th Flotilla.
Why go down the road of conspiracy? Iran has been deploying warships on anti-piracy patrols into the Red Sea and Gulf of Aden since 2008. The Iranian Navy also made a port call in Saudi Arabia during 2011 when they last went into the Mediterranean. The Saudi's have been very grateful to the Iranians due to them thwarting piracy attempts on Saudi ships.
During 2011 the Iran Navy also made a port call to Saudi Arabia. The Iranian vessels also completed a visit to Tartus, Syria during 2011.

Why would the Iranians take the risk of being caught red-handed with vessels stockpiled with weapons by the Egyptian authorities? All it would take would be for the Egyptian authorities to request a courtesy search and the Iranians would be caught out. The Iranians would have no option but to refuse and be denied transit. IMHO, the Iranians are only transiting the Suez as a poke in the eye to the Israeli's. They know that if they keep everything above board and professional then nothing can be done in regards to their use of the Suez. The visit to Syria at this time is also seen as direct support to Syria and further annoyance to Israel and the US.
Recent news has the Iranian vessels jamming Syrian Free Army communications during their brief visit.
